DITCHING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 270,987, dated January23, 1863.

Application filed September 15, 1882. (Novmodcl.)

To all whom it may concern Be it known'that I, NATHANIEL E. ROSS, acitizen of the United States, residing at Versailles, in the county ofDarke and State of Ohio, have invented a new and usefulDitching-Machine, of which the following is a specification, referencebeing had to the accompanying drawings.

Figure l is a plan view of my improved ditching-machine. Fig. 2 is afront view of the same. Fig. 3 is a longitudinal vertical sectionalview, and Fig. 4is a vertical transverse section.

Corresponding parts in the several ligures are denoted by like lettersof reference.

This invention relates to ditching-machines; and it consists in certainimprovements in the construction of the same, which will be hereinafterfully described, and particularly pointed out in the claim.

In the drawings, A represents a rectangular frame, mounted upon thefront and rear axles, B C, the former of which is swiveled under thefront end ofthe frame upon the king-bolt D., while the latter revolvesin suitable boxes, E, under the rear end ofthe frame. The front wheels,F, are loose and the rear wheels, G, fixed upon their respective axles.

Between the front beam of frame A and a transverse cross-beam, H,near'the latter, is fitted a block, I, having bearings for avertically-slidin g frame, J, carryinga vertical rackbar, K. Uprights Lupon block I have bearings for a shaft, M, provided with a crank, N, andhaving alpinion, O, engaging the rack K. Shaft M also has aratchet-wheel, P, engaging a pawl, Q. By this mechanism the frame J maybe raised or lowered and retained at any desired elevation.

The sides of frame A have downward-projecting brackets or hangers B,support-ing a transverse frame, S, which consists essentially of twoside pieces connected b'y suitable braces. Said frame S is capable ofsliding in the hangers or brackets R longitudinally in relation to frameA. The sides T of frame S extend from one end of the latter to near theground, and at the upper and lower ends are journaled shafts U V, uponwhich runs an elevator-belt, W. The front side, T, of frame S has bearlupper end of an elevator-frame, Y, having at its lower end a shaft, Z,upon which and shaft X the belt A', having suitable carrying-buckets, ismounted. y.

B' is a prismatic shaft, mounted in the crossbeamA H and in a transversebeam, C', connecting the brackets R in such a manner that it may be slidfor a short distance longitudinally in its bearings by means of a forkedlcver, D', engaging a groove, E', in said shaft. Shaft B' has at itsrear end a pinion, F', receiving motion from a gear-wheel, G', fixedupon the rear axle of the machine, but capa- 4ble of being thrown out ofengagement by sliding the shaft rearwardly. Mounted loosely upontheprismatic shaft, in such a manner as not to interfere with itssliding motion, is a gear-wheel, H', having teeth both upon its side andedge, engaging pinions I' J' upon the shafts V and X, thus operating theelevatorbelts W and A', respectively.- A small suitably-constructedframe, K', contines the gearwheel H' closelybeside frame S.

To the lower end of .the elevator-frame Y i's hinged the ditching-scoopL', which in turn is suitably connected to the lower end ofthevertically-adjustable frame J.

The operation of my invention will be readily understood from theforegoing description, taken-in connection with the drawings heretoannexed. By raising or lowering the frame J the ditching-scoop may beadjusted so as to dig a ditch of any desired depth, the elevator-frame Ybeing simultaneously adjusted so as to convey the dirt to the elevatorYV,

by which it is deposited at the side of the ma-4 chine. lhen theelevator Y is raised orlowered the frame S of elevator W slideslongitudinally in the brackets B, so as to permit the desired adjustmentwithout interfering with the operation of the machine.

I claim and desire to secure by Letters Patent of the United States- Thecombination of the frame A, the longitudinally-sliding transverseelevator-frame S, having operating-shaft V, provided with pinion I', theshaft X, having pinion J', longitudinalelevator-frame Y, having hingedditching-scoop L', verticallyadjustable frame J,
